The integrated fan control (IFC) board orchestrates every stage of system operation — managing blower motor speeds, sequencing heating and cooling calls from the thermostat, monitoring safety inputs, and executing timed off-delays that protect the heat exchanger and evaporator coil. When this board fails, common symptoms include the blower failing to run on any speed, the system locking out with fault codes, erratic fan cycling, or a complete loss of heating and cooling response despite correct thermostat signals.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number HK61EA006 | Factory fan blower control board | Multi-speed blower motor control | 24V control circuit input | Integrated fault code diagnostic LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-original Carrier board — firmware, relay ratings, and terminal layouts are an exact match for the PF1MNB036008AAAA.
